From and after the passage of this article,
it shall be unlawful for any persons to install a building sewer to
connect to the public sewer in the Township of Lower Providence without
having first obtained from the Board of Supervisors a certificate
of license to engage in such work.
For the purpose of these regulations, that portion
of a building (or house) drainage system extending from a point three
feet outside of the building wall to the public sewerage system is
considered to be a building sewer. All sewers falling within this
category shall henceforth be installed in accordance with the following
rules, regulations and requirements:
A. Materials.
(1) Building sewers shall be constructed of any one of
the following materials, except as noted below:
(a)
Cast-iron soil service, weight conforming to
ASTM Designation A74-42, installed with cast lead.
[Amended 6-11-1984 by Ord. No. 306]
(b)
PVC plastic sewer pipe. All plastic pipe and
fittings shall conform to ASTM Designation D3034, Schedule 80, installed
with push-on-type gasket joints conforming to ASTM Specification D3212
or solvent cement joints complying with ASTM Specification D2855.
Gaskets for push-on joints shall conform to ASTM Specification F477.
[Added 6-11-1984 by Ord. No. 306]
(2) All materials shall be clearly marked and identified,
and conformance with the specification requirements shall be certified
by the manufacturer. With the exception of adapters, the entire building
sewer shall be constructed of the same type of material. Whenever
sewer pipe is laid under driveways or parking areas, extra-heavy cast-iron
pipe shall be used.
(3) Lower Providence Township and/or the Lower Providence
Township Sewer Authority may require the use of cast-iron pipe for
building sewers where conditions are not suitable for plastic pipe.
[Added 6-11-1984 by Ord. No. 306]
B. Size and slope. Building sewers shall have a minimum
inside diameter of four inches and, in general, shall be installed
on a slope of at least 1/4 inch per foot. Where the available
fall is limited, however, the slope may be reduced to a minimum of 1/8
inch per foot.
C. All building sewers shall be installed in separate
trenches and in no case shall they be installed in the same trench
with a water service line. The width of the trench shall not exceed
24 inches at a point four inches above the top of the sewer. All trenches
shall be of sufficient depth to provide a minimum cover of 30 inches
over the pipe. In the event that it is impossible to provide a minimum
cover of 30 inches over the pipe, then a cover of a lesser depth shall
be permitted upon the joint approval of the Engineer for the Lower
Providence Township Sewer Authority and the Engineer for Lower Providence
Township. Trench bottoms shall be carefully prepared and holes shall
be dug for the pipe bells or couplings in such a manner that the pipe
will bear on undisturbed earth for the entire length of the barrel.
Where rock is encountered, it shall be removed for a depth of four
inches below the outside of the pipe barrel and replaced with clean
earth or approved fill to provide a proper pipe bedding.
[Amended 3-6-1967 by Ord. No. 87]
(1) When plastic pipe is used, it must be bedded in a
minimum of four inches of 1B or AASHTO-8 stone.
[Added 6-11-1984 by Ord. No. 306]
D. Backfilling.
(1) After the pipe has been installed, tested and inspected,
the trench may be backfilled. To a point one foot above the top of
the pipe, the backfilling shall be done in four-inch layers, each
layer to be thoroughly tamped and compacted.
(2) Where the building sewer is connected to the public
sewerage system, the entire depth of backfill shall be thoroughly
tamped in four-inch layers in such a manner as to avoid settlement
at the curbline or edge of pavement. Such tamping shall be done from
the curb or road paving edge for a horizontal distance of twice the
depth of the pipe.
(3) When plastic pipe is used, it shall be backfilled
to a minimum depth of six inches with 1B or AASHTO-8 stone above the
top of the pipe. From a point six inches above the crown of the plastic
pipe, the backfill material shall be clean earth free from rocks larger
than six inches in diameter.
[Added 6-11-1984 by Ord. No. 306]
E. Cleanouts. A cleanout fitting shall be installed outside
of the building where the sewer is connected to the building drain.
The cleanout fitting shall be brought to grade to provide maximum
accessibility for sewer cleaning.
F. Fittings and adapters. Changes in direction at any
one point shall be effected with a forty-five-degree angle or a long
sweep bend not exceeding a ninety-degree angle and shall be made with
appropriate fittings at least equal in quality to the straight pipe.
Connections to the public sewerage system shall be made by means of
a special adapter of a type approved by the Authority.
G. Grease traps. Grease traps shall be installed wherever
a connection is made to a restaurant or a building subsequently used
as a restaurant.
H. Tests. Before acceptance, each building sewer shall
be plugged and subjected to an internal water pressure equivalent
to a head of four feet. This test shall be performed in the presence
of the Authority's authorized inspector. Evidence of excessive leakage
shall be sufficient cause for rejection of the sewer installation.
When the building sewer has been installed but
before connection to the public sewer has been made, a licensed plumber
or plumbing firm shall make arrangements with the Township of Lower
Providence Sewer Authority's authorized inspector to inspect the installation
and witness the hereinbefore described test. If the excavation is
of the proper width and depth, the sewer materials comply with the
requirements of this regulation, the sewer is laid to the proper grade
upon an adequate foundation and the joints are properly made and tight,
the Authority's authorized inspector will indicate his approval, after
which the connection to the public sewer may be made. When the latter
connection has been completed to the satisfaction of the Authority's
authorized inspector and the excavation properly backfilled, he will
issue a certificate of approval of the installation.
In the case of new sewer construction to be
connected with the sanitary sewer system, a lateral permit shall be
obtained from the Sewer Authority before any part of the work shall
be commenced.
The certificate of registration granted under
this article may be suspended or revoked by the Board of Examiners
when any firm or corporation or a registered representative thereof
shall violate any of these rules and regulations and shall refuse
or neglect to make the necessary corrections to work not approved
by the Authority's authorized inspector, within a reasonable time
after notification thereof, or shall permit the use of his, their
or its name by a person or persons for the purpose of obtaining a
permit or permits for installing building sewers to the public sewer
in Lower Providence Township. No person, firm or corporation carrying
on the business of installing building sewers to the public sewer
of Lower Providence Township shall allow his or their name to be used
by any person, directly or indirectly, either to obtain a permit or
permits or to do any work under his or their license.
This township reserves the right to adopt, from
time to time, additional rules and regulations as it shall deem necessary
and proper relating to connections with a sewer and the sewer system,
which additional rules and regulations, to the extent appropriate,
shall be and shall be construed as part of this article.
[Amended 3-14-1983 by Ord. No. 295]
Any person who shall violate this article shall
be liable, upon summary conviction for a first offense and upon summary
conviction for each subsequent offense, to a fine of not more than
$300, together with costs of prosecution in each case. Each day that
a violation shall continue shall be deemed and shall be taken to be
a separate offense and shall be punishable as such.
It is declared that enactment of this article
is necessary for the protection, benefit and preservation of the health,
safety and welfare of the inhabitants of this township.
